domain of f(x)=-2/(x-1)

domain

f (x) = - \frac{2}{x - 1}

x < 1 or x > 1

Interval Notation

(- \infty, 1) \cup (1, \infty)

Solution steps

Find undefined (singularity) points:

x = 1

The function domain

x < 1 or x > 1

\frac{7 x}{9 x - 1}

1 + x - 2

y = \frac{4}{x - 1}

\frac{1}{( x + 1 ) ^{2}}

(y - 3) = - \frac{3}{4}

What is the domain of f(x)=-2/(x-1) ?
The domain of f(x)=-2/(x-1) is x<1\lor x>1
